"Little confidence can be placed in
these relationships although, surprisingly, they are all chronologically possible except for 'Mam Tudur Trefor' and "Mam Llywarch
Gam'. To the best of my knowledge [the second pedigree] does not appear again until Lewys Dwnn who gives an expanded
version (ii.307)."

PEDIGREE 1:

For those whose Welsh isn't
fluent, we shall attempt to render the pedigree in English:

"The mother of Tudor Trevor[1]
was Reingar ferch Lluddocca ap Caradog Freich Fras, earl of Hereford, ap y Ceiliog Myngrudd of the North ap Eidol Darian Las
ap Ceneu ap Coel Godebog. Tudor Trevor had three sons, namely, Gronwy, Lluddocca and Dyngad. Gronwy had a daughter
and heiress named Gwen, who was the mother of Elystan Glodrydd. This Elystan Glodrydd became earl of Hereford by right
of his mother since Tudor Trevor had inherited it from his mother, the daughter of Lluddocca ap Caradog Freich Fras, earl
of Hereford."

While Reingar was the granddaughter
of Caradog Freich Fras, he was not the man of that name who lived in the 6th century near Hereford whose flawed pedigree follows
that name. She was a lady of north Wales whose grandfather was the Caradog Freich Fras of c. 820 found in the pedigree
of Heilig ap Glannog. This misidentification led early historians to believe Tudor Trevor held lands in Hereford, whereas
his lands were all north of the Severn in Cheshire and Shropshire.

Gronwy ap Tudor Trevor died
before his father; his only daughter, Gwenllian, married a man of southeast Wales named Cuhelyn ap Ifor and she was the mother
of Elystan Glodrydd who became King of Fferlys. That kingdom lay between the Wye and Severn, south of Powys and north
of Gwent. It did, prior to the Norman incursions, extend east into Herefordshire.

PEDIGREE 2:

The first item is a repeat from
the first pedigree, but deletes all the wording which misidentified the Caradog Freich Fras in the ancestry of Tudor Trevor's
mother. Reingar was born c. 885.

The second item identifies the
wife of Tudor Trevor by calling her the mother of his son, Lluddocca. Angharad ferch Hywel Dda was born c. 915.

The fourth item identifies the
wife of Llowarch Gam ap Lluddocca. Nest[3] was born c. 980 and was a sister of Cynfyn ap Gwerystan and aunt of Bleddyn
ap Cynfyn.

Had Bartrum correctly identified
the Caradog Freich Fras and the Iago ap Idwal mentioned in the pedigrees, he could not have concluded that ANY of the relationships
cited were chronologically impossible; while slightly corrupt as cited, the marriages were not only possible but highly probable.
Tudor Trevor was descended from a junior branch of the First Powys Dynasty, held a vast lordship in the lands bordering Wales
and Mercia, and his family should be expected to have married neighboring nobility.

NOTES:

[1] Tudor was called "trefor" because he was born at Tref Awr, a manor
in Nanheudwy near the present Llangollen

[2] She is called Angharad in Dwnn ii, 307

[3] This lady is called Lleuci in Dwnn ii, 307

[4] The ancestry of Gwrgeneu extends back to Cadell ap Cynan Garwin of the
First Powys Dynasty; Cadell was a younger brother of King Selyf and both fell in the 613 Battle of Chester

[5] Llyddoca was a brother of Gwgan Gleddyfrudd who is found in the pedigree
of Heilig ap Glannog

[6] Dyngad was the eldest son of Tudor Trevor and inherited the northern part
of the lordship, principally Maelor. Lluddocca received his father's manor and the part of his lands which extended
south to the Severn; except for Nanheudwy, those lands were all in present-day Shropshire. The third son, Goronwy, died
during the lifetime of Tudor and thus inherited nothing

[7] Ifor was the son of Seferys ap Cadwr. His sister, Sissely, married
Dyngad ap Tudor Trevor. This family descended from Tegonwy ap Teon and represented the southern branch of the extended
Powys family

[8] Gwaithfoed of Powys represented another branch of the family descended from
Tegonwy ap Teon; his descendant, Bleddyn ap Cynfyn, founded the Second Powys Dynasty. The first-cousin of Gwaithfoed
was Gwrydr Hir ap Caradog ap Lles Llydog; that Gwrydr Hir married Arddun, a daughter of Tudor Trevor
